// NOTE: if you are getting error like "invalid image" related to loading the SDK's dll then
// try to do the following:
// 1) remove the reference to the SDK by View - Solution Explorer
// then click on References, select Bytescout... reference name and right-click it and select Remove
// 2) To re-add click on the menu: Project - Add Reference
// 3) In "Add Reference" dialog switch to "COM" tab and find Bytescout...
// 4) Select it and click "Add"
// 5) Recompile the application
// Note: if you need to run on both x64 and x86 then please make sure you have set "Embed Interop Types" to True for this reference
